Behavioral ecotoxicological assessments in freshwater ecosystems allow early pollution detection and are highly sensitive to environmental changes. We assessed changes in general activity, exploration, foraging, and group cohesiveness of Galaxias maculatus in response to 2,4-dichlorophenol.
Article
Diplomystidae is an early-diverged family of freshwater catfish endemic to southern South America. We have recently collected five juvenile specimens belonging to this family from the Bueno River Basin, a basin which the only previous record was a single juvenile specimen collected in 1996. This finding confirms the distribution of the family furth...
Chapter
Northern Patagonian River systems located between the Araucanía and the Los Lagos Regions of Chile are characterized by lake regulation and seasonal predictable flow regime. As these systems originate in large glacial lakes, their flow velocities are lower compared to other Andean River systems in Chile. The San Pedro River (Valdivia River basin) i...

The effects of human-induced stressors on riverine fish assemblages are still poorly understood, especially in species-poor assemblages such as those of temperate South American rivers. In this study we evaluated the effects of human-induced stressors on the taxonomic and functional facets of fish assemblages of two central-southern Chilean rivers:...

Full-text available
Salmonid introductions for sport fishing and, more recently, for farming, have had a large impact on freshwater ecosystems in many regions worldwide. In Patagonia, both activities have contributed to the colonization of freshwater systems particularly by species such as Brown Trout (Salmo trutta) and Rainbow Trout (Oncorhynchus mykiss). The ecologi...

Utilizando el concepto de Ecosistema de Referencia se evaluó el estado de componentes del ecosistema en el origen del río Maullín, en la Región de los Lagos.
Article
• Understanding of trophic structure and flow of energy within river systems is essential for informed management of these ecosystems and conservation of native fish fauna and fisheries resources. Food resources used by riverine fish depend on productivity within the main stem and adjacent floodplains, terrestrial inputs, and longitudinal and later...
Article
Full-text available
The ancient catfish family Diplomystidae, with seven species endemic to rivers of southern South America, represents one of the oldest branches of the diverse order Siluriformes. With most species endangered, new reports of these species become extremely valuable for conservation. Currently, it is assumed that Diplomystes species inhabit only Andea...
Article
Mediterranean rivers are characterised by strong environmental constrains and species-poor, highly endemic fish fauna. In Europe, these systems are exposed to multiple stressors due to extensive human activities. Studies on the effects of some stressors on riverine fish are available but complex responses of fish assemblages to interplay of flow al...

Resumen ejecutivo Los ecosistemas de agua dulce o humedales presentan una enorme diversidad en Chile, desde bofedales, vegas y salares en el norte a bosques pantanosos o hualves, ñadis y turberas en el sur, incluyendo lagos, lagunas, pantanos, ríos, esteros y arroyos, entre otros. Todos ellos tienen en común contar con un cuerpo de agua permanente...
Conference Paper
Full-text available
Land-use changes often have significant effects on river flows and sediment yields from specified catchment. Thus, land-use changes have ecological implications not only for the health of terrestrial but also for aquatic ecosystems. Over the last decades, south-central Chile has suffered a drastic replacement of native forest by exotic forest plant...
Article
Mediterranean rivers are strongly affected by pollution and water scarcity. Over the summer period, urban and industrial effluents arrive into the rivers with little dilution. In order to assess the water quality, two native fish species, Barbus meridionalis and Squalius laietanus, were collected from six sites along the Ripoll River (Spain). PAH m...

Full-text available
Trait-based ecology has been developed for decades to infer ecosystem responses to stressors based on the functional structure of communities, yet its value in species-poor systems is largely unknown. Here, we used an extensive dataset in a Spanish region highly prone to non-native fish invasions (15 catchments, N = 389 sites) to assess for the fir...

We document movement patterns and home range of Diplomystes camposensis, an endemic and threatened freshwater catfish from Chile. We tracked the movements of seven individuals of different body size (13.5 to 19 cm SL) using portable radio telemetry equipment to investigate movement patterns in relation to day/night activity and habitat use in the S...
Article
Recycled water is important for maintaining river flow in semi-arid regions. However, it has ecological risk, as suggested by comparison of habitat and white and red blood cell count in two wild fish species (Barbus meridionalis and Squalius laietanus) before and after an input of recycled water in Ripoll River (NE Spain) in 2009. Due to the lack o...
Article
The textile industry is one of the largest sectors globally, representing up to 20% of industrial water pollution. However, there is limited insight into how fluvial ecosystems respond and recover from this impact. From summer 2012 to spring 2013, we examined water quality and ecological status upstream and 1.5 km downstream the input of a textile...
Conference Paper
Full-text available
Mediterranean Rivers have experienced a long-history of anthropogenic impacts. Water pollution is still one of the major threats to freshwater biota despite the marked investments in sewage treatment plants (STPs) in recent decades. This is attributed, in part, to the reduced water flow of these systems due to climate and water abstractions, couple...

The Chilean native fish are characterized for having small sizes (< 30 cm). Due to this, they are generally described with a low swimming capacity and movement; nevertheless, there is no empirical study to show it. In this study we describe the movement patterns of six native species in the San Pedro River (Aplochiton taeniatus, Galaxias maculatus,...
